I really like the simplicity of this shot. Reminds me of childhood.

I think this is a pretty cool shot. I really like the texture in the grouind and the colors in the picture. I think that the framing of it works well to, especially with the fork coming in at a good angle. I would probably brighten it up a bit though. Since everything is in shadow you have a long ways to go before the whites in the wheel start losing any detail. Brightening it up would help out the colors to pop just a little bit more. I like simplicity in general, but here I think it is too simple. Even to the point that I lose perspective a little bit, I start to wonder how that thing is standing up, because I have no frame of reference as to how it is being held up. Showing some more of the bike may have helped this out. Over all this is a nice take on the theme.

simple, but yet fits the challenge well. I like the different colors but i think they need a little "pop". I really like the texture of the ground. It really adds to the picture.

I like the composition of the shot...but there is a strange color cast?

I like this... I think I had a bike similar to this one!

I do see a bit of a blue cast, easy fix though. You could try adding a warming photo filter in photoshop and that should fix that cast right up! Probably will help and add a little "pop" to the image as well.

I agree with most of the comments, esp Farrah. I think the pic looks a little "blue" and not sure that was the intent. I'm guessing the sun was setting. I like the wear on the tread - looks new but still worn at the same time. I really like the bricks for contrast too.

I like this shot.... much more interesting than including the whole bike. I do feel like it is cropped a little too tight though.
